Vulnerability from github – Published: 2024-10-23 18:33 – Updated: 2024-10-24 21:31

Details

Botan before 3.6.0, when certain LLVM versions are used, has compiler-induced secret-dependent control flow in lib/utils/ghash/ghash.cpp in GHASH in AES-GCM. There is a branch instead of an XOR with carry. This was observed for Clang in LLVM 15 on RISC-V.

Severity ?

5.9 (Medium)
